MicroRNAs are small, non-coding transcripts that control gene expression by preventing mRNA from translating into proteins. They have been implicated to play a role in many drug addictions. We previously found that miR-495 targets several addiction-related genes (ARGs) and is highly expressed in the nucleus accumbens (NAc). We also found miR-495 is downregulated in the NAc following acute cocaine administration, and cocaine motivation measured by breakpoint on a progressive ratio schedule of cocaine reinforcement is decreased when miR-495 is overexpressed.
